2 ways to invoke the debugger:
- launching debugger once a program is called and reaching a specific line number:
Launch a “Break” command (or Shift + Backspace if break is de-activated) then: B <space> line nb , program name‘ The line number should correspond to an instruction line (not a comment!). The debugger has then recorded this process stop. Strike ‘”C”‘ to continue & quit the debugger. Execute all required actions in T24, if the specified program is called and pass though the line number indicated, debugger will be prompted.
Example :
B 127,MM.MONEY.MARKET
will invoke the debugger in the “MM.MONEY.MARKET” the program and will stop on line 127.
- adding “DEBUG” directly in a program.
Useful Instructions keys:
P : set the source path; useful when line numbers are different between debug/source. Example: “P BPT”
S : go to next instruction. s : go to next instruction, + enter in all CALL / GOSUB.
C : finish the program execution.
V : <variable> : display a variable content.
V -M : <variable> : allows to dynamically assign a value to a variable (debugger will prompt for a value).
W : show where you are in the program (current line +/- 5 lines).
J -G : show all program context
B : display all break points. You can add a new breakpoint during the debug itself.
D delete all break points set (or to get out from a loop).
Delimiter displayed:
| delim. | using debugger | using a CRT | ASCII | delim. type |
| IM | _ | 255 | 1 | |
| FM | ^ | ؟ | 254 | 2 |
| VM | ] | ÿ | 253 | 3 |
| SM | \ | ü | 252 | 4 |
| TM | \373 | û | 251 | 5 |
“delim. type” is returned for example by “REMOVE var FROM array SETTING delim. type”
